Abstract: The invention discloses a voice quality evaluation method and device. In the voice quality evaluation method, a voice quality evaluation model is established in advance, voice data to evaluated is obtained, a network evaluation feature and/or a voice evaluation feature of voice data to evaluated is extracted, the network evaluation feature and/or voice evaluation feature of voice data to evaluatedare/is input to the voice quality evaluation model established in advance, and an evaluation result of the voice data to evaluated is obtained in real time. Thus, a voice signal output by a communication network serves as the voice data to be evaluated so as to obtain the evaluation result, and the voice signal quality of the communication network is monitored accurately in real time.
